To: linux-kernel@vger.kernel.org Message-id: <873d059gzh.fsf@frobnitz.ddts.net> MIME-version: 1.0 Content-type: text/plain; charset=US-ASCII Content-transfer-encoding: 7BIT Mail-Copies-To: schepler@math.berkeley.edu User-Agent: Gnus/5.0808 (Gnus v5.8.8) XEmacs/21.4 (Common Lisp) Lines: 25 Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Lately, whenever I try to access a certain part of my hard drive, I get messages like: Feb 12 21:16:27 localhost kernel: hdc: read_intr: status=0x59 { DriveReady SeekComplete DataRequest Error } Feb 12 21:16:27 localhost kernel: hdc: read_intr: error=0x01 { AddrMarkNotFound }, LBAsect=34508632, sector=32410984 Feb 12 21:16:27 localhost kernel: ide1: reset: success Feb 12 21:16:27 localhost kernel: hdc: read_intr: status=0x59 { DriveReady SeekComplete DataRequest Error } Feb 12 21:16:27 localhost kernel: hdc: read_intr: error=0x01 { AddrMarkNotFound }, LBAsect=34508632, sector=32410984 Feb 12 21:16:27 localhost kernel: end_request: I/O error, dev 16:02 (hdc), sector 32410984 except that the first two messages are repeated several more times, at intervals of a few seconds. Also, during the first bad access, DMA gets disabled. While this is going on, the system load goes way up, and I don't seem to be able to do anything else. Is this typical behavior for a hard drive which has developed bad blocks? And if I blacklist the affected blocks in the filesystem, should I also blacklist a few previous blocks in order to avoid problems with the readahead feature of the IDE drivers?
